Killing anyone with magick is difficult and, to be frank, aren't there a lot of non-magical ways to kill yourself that are way easier? Even side from how tragic and foolish suicide is, why in the world would you use magick to do it!?

Why would you want to do that ? Your situation sounds really bad if you are considering to suicide by using any form of magic. And lets not forget that when you cast a death spell on someone he/she does not just drop dead. Perhaps you do not know how all of it works.

Secondly, I really think that you need help. Please see a doctor / psychologist so you would be able to improve your psychological condition. Wanting to suicide is a very hard thing which requires psychological help, not to talk about how dangerous it is. Have you thought about how many things you could miss by losing your life? I really think that you need all of the best help that can be offered by psychologists and other therapists, wanting to suicide by using magic or any form of hurting yourself is a terrible thing that you must overcome and get all of the help you can !

"can you cast a death spell on yourself
to cuse your own death
thanks"
Now read it slower
>Can you cast a death spell on yourself to cure your own death
>On your to cure your own death
>Cure your own death
I think they are asking to avoid death but I'm not sure as I don't think English is their first language

The word cuse is missing the letter a, cause is what was meant. Don't make such a deal out of it.
And as for death spell for yourself, don't do it. If you are having problems, find someone to talk to, professional or not. Something bothering you to make you feel death is the answer is not worth death. You are alive and need to enjoyit. See the enjoyment, the wonder of it all, the awe of life itself. May you find your true answer. Blessed Be...
